Is Soul Suspect A Murder Mystery Game From Square Enix?

Square Enix might be working on a new game called Soul Suspect or maybe Murdered: Soul Suspect. The Final Fantasy publisher filed a trademark for Murdered Soul Suspect in Japan, which sounds like a murder mystery game to us.

Perhaps, players will control a recent murdered victim’s soul and have to search for the suspect? Considering how well the murder mystery setting worked for Persona 4, we’d welcome another role playing game with a similar setting.
